Add digit by digit: ABC + DB1 ------ 186D C+1=D B+B=11+11=22=6 with carry A+D=10+13+carry=24(base 10)=18 (hex)

how is (b+b)=22?
OpenStudy (mathmate):
Sorry, let's start over: Add digit by digit: ABC + 2F5 ------ DB1 C+5=12+5=17(base 10) = 1 with carry B+F+carry=11+15+carry=27(base 10)=B with carry A+2+carry=D
OpenStudy (mathmate):
B(hex)=11(10) So 11(10)+11(10)=22(10)=16(hex)
